Definitions
- the invention relates to a method for measuring at least one preloading force that acts between a shaft and a rolling-element bearing of a bearing assembly mounted on the shaft.
- the invention also relates to a bearing assembly for performing this method.
- the force measurement device is a sensor element constructed as a force measurement film with a profile thickness between 0.02 and 0.7 millimeters. It can be inserted into arbitrarily constructed recesses on rolling-element bearings or in intermediate elements connected to rolling-element bearings or surrounding the entire bearing.
- the force measurement film can be used for detecting a static and also a dynamic force measurement in the axial and radial direction.
- the invention is based on the object of providing a method with which a rolling-element bearing can be mounted with a defined preloading force economically and correctly and reliably on a shaft. This objective is achieved by a method for measuring the preloading force and by a bearing assembly having one or more features of the invention. Preferred or advantageous embodiments of the invention are produced from the subordinate claims, the following description, and/or the accompanying figures.
- a method for determining at least one preloading force acts between a carrying body and a rolling-element bearing of a bearing assembly mounted on the carrying body.
- an axial preloading force is measured for and/or during the mounting of the rolling-element bearing on the carrying body directly or indirectly with the method.
- the carrying body is constructed as a shaft or axle.
- the rolling-element bearing is preferably constructed as a conical roller bearing or ball bearing, in particular, as an angular contact ball bearing.
- the rolling-element bearing has an inner ring, multiple rolling-element bodies, and an outer ring.
- the bearing assembly comprises the rolling-element bearing and at least one sensor device.
- the bearing assembly comprises at least one evaluation device.
- the sensor device is arranged in an installation position in or on the rolling-element bearing and is coupled with the evaluation device by signals.
- the sensor device in the installation position can be connected to the evaluation device and detached from the evaluation device again.
- the sensor device preferably has a coupling interface and the evaluation device has a coupling counter interface.
- the sensor device detects the preloading force during or after the mounting of the rolling-element bearing on the carrying body. As a function of the detected preloading force, the sensor device generates at least one signal and transmits this, in particular, via the coupling interface connected to the coupling counter interface, to the evaluation device.
- the evaluation device evaluates the signal for measuring the preloading force.
- the evaluation device outputs the value of the preloading force optically and/or acoustically.
- the sensor device is permanently decoupled from the evaluation device after the evaluation of the signal.
- the coupling interface is separately permanently from the coupling counter interface.
- the method according to the invention a reliable, correct, and efficient measurement and setting of the preloading force can be realized in the mounting of the rolling-element bearing on the carrying body. It is especially advantageous that the method is suitable for series production. It is also advantageous that the rolling-element bearing can be driven together with the sensor device arranged in the installation position in the rolling-element bearing as a marketable unit.
- the sensor device remains in the installation position after the transmission and/or evaluation of the signal.
- the sensor device is here decoupled from the evaluation device.
- the sensor device and/or the coupling interface is destroyed during the decoupling of the evaluation device.
- the sensor device is destroyed during the operation of the rolling-element bearing, for example, by forces acting on the sensor device in the installation position, in particular, by one or more rolling-element bodies of the rolling-element bearing.
- An alternative, possibly preferred processing step provides that the sensor device is removed from the rolling-element bearing after the transmission and/or evaluation of the signal.
- the sensor device is located in a loose installation position, whereby it is detachable from this position without a tool.
- the sensor device is loosely placed, pushed in, or inserted into the installation position.
- the sensor device has a gripping aid that is constructed, for example, as a lug projecting from the sensor device.
- the lug is accessible from outside of the installation position, so that this can be gripped and the sensor device can be pulled out from the installation position.
- An optional embodiment in the scope of the method is to reuse the sensor device after the removal from the installation position for the mounting of at least one other rolling-element bearing on one shaft or the shaft. This has the advantage that costs can be spared for additional sensor devices.
- the sensor device is constructed as a film, preferably as a measurement film, in particular, as a polyvinylidene fluoride film (PVDF film). It is also possible that the sensor device is constructed as a single-layer or multi-layer measuring strip or as a single-layer or multi-layer measuring plate. In this way, the sensor device is relatively thin and/or flexible and can be arranged in a simple way and without limiting the function on the rolling-element bearing in the installation position and optionally can remain permanently there. Alternatively, the sensor device can be formed as a measuring pin or measuring peg. This has the advantage that the sensor device can be arranged with an accurate fit and without limiting the function of the rolling-element bearing in at least one hole in the inner and/or outer ring of the rolling-element bearing and optionally can remain there permanently.
- PVDF film polyvinylidene fluoride film
- the sensor device constructed especially in at least one of the described embodiments as a piezoelectric, inductive, or photoelastic sensor.

- the sensor device In the case that the sensor device is permanently left in the installation position, it is formed, e.g., as a so-called lost sensor.
- the sensor device is arranged on the inner ring and/or on the outer ring of the rolling-element bearing.
- the sensor device is arranged, in particular, on an axial surface and/or end face surface of the inner and/or outer ring.
- the sensor device is arranged in a hole on the inner and/or outer ring.

- the sensor device is formed preferably as the film or as the measuring strip. Because the sensor device preferably has a very small thickness in this construction, it is especially suitable for the arrangement on the raceway. If the sensor device remains in the installation position after decoupling from the evaluation device and is not removed from this position, the sensor device is typically destroyed by the constant rolling of the rolling-element bearing or bearings, if this does not already happen due to the decoupling.
- the senor device is also positioned between two rolling-element bearings, e.g., arranged in an X or O arrangement on the shaft and detects the preloading force there.
- the axial preloading force can be determined based on the running surface of the rolling-element body running at an angle relative to the carrying body.
- the running surface of the conical rollers has a conical construction. Due to the angular construction of the running surface for the angular contact ball bearing or the conical running surface for the conical roller bearing, these rolling-element bearings receive the same radial and axial loads.
- the axial preloading force can be determined directly or indirectly by detecting and evaluating the axial load.
- multiple sensor devices are arranged in multiple or also different installation layers in or on the rolling-element bearings. It is also possible that the multiple sensor devices differ in their construction and/or function. Through a location-resolved arrangement of the multiple sensor devices in the multiple installation positions, different measurement points can be provided. This can lead, in particular, to more reliable and more exact measurement results.
- the coupling interface of the sensor device is arranged and/or constructed accessible from outside the installation position.
- the evaluation device can be coupled by means of the coupling counter interface in a simple way with the sensor device, in particular, in the scope of series production.
- the coupling interface is constructed as a socket and the coupling counter interface is constructed as a connector. It is also possible that the coupling interface is constructed as a lug extending out from the installation position.
- the corresponding coupling counter interface is constructed as a gripper and/or as a clip.
- the evaluation device can be decoupled from the sensor device without destroying this sensor device.
- the sensor device and/or the coupling interface is destroyed for the decoupling of the evaluation device from the sensor device. This is especially the case when the evaluation device is cut away, for example, from the sensor device.
- Another object of the invention relates to a bearing assembly that is constructed, in particular, for performing the method according to the invention.
- the bearing assembly comprises the rolling-element bearing and the at least one sensor device.
- the bearing assembly also comprises the evaluation device.
- the bearing assembly provides that the sensor device is arranged on the raceway of at least one of the rolling-element bodies. Alternatively or optionally additionally the sensor device has a lug that is accessible from outside the installation position as the coupling interface and/or as the gripping aid.
- the rolling-element bearing has the sensor device that is destroyed and remains in the installation position after the mounting on the shaft that is performed with the measurement of the preloading force.
- This sensor device is optionally destroyed by the decoupling of the sensor device from the evaluation device.
- the sensor device is/was destroyed during the operation of the rolling-element bearing.
